ORONO, Maine — Erring on the side of caution, University of Maine police called the Bangor Police Department’s bomb squad Monday night to remove six sealed pieces of PVC pipe found in a chemistry lab, police and university officials said.

The squad removed the items, which resembled small pipe bombs, and indicated to UMaine officials that there was no danger, university spokesman Joe Carr said Tuesday.

“They just took them to dispose of them,” Bangor police Sgt. Paul Edwards said Tuesday. “They did it as a precaution.”

Personnel from UMaine’s Department of Environmental Health and Safety were cleaning a laboratory on the second floor of the Edward T. Bryand Global Sciences Center on Grove Street when they discovered what they feared were pipe bombs at around 7 p.m. Monday, Carr said.

The cleaning crew “noticed six small pieces of PVC pipe that were about one-inch long, sealed on each end,” Carr said.

University police responded to the lab and decided to call in the local bomb experts — Bangor’s bomb squad, he said. The building was not evacuated.

Bomb squad officials indicated that the PVC pieces probably were not a danger, Carr said.

“We where told they did not believe they were dangerous,” he said.

The components of the PVC pipe pieces are not known, but they will not go to waste, Edwards said.
